摘要: 基于线性矩阵不等式(LMI,1inear matrix inequalities),考虑了线性时不变对象的一类 控制问题的降阶控制器设计问题.给出了一个新的降阶控制器阶的上界,该上界适用于标准和 奇异控制两种情形.证明是构造性的,可以给出降阶控制器的构造方法.给出了简单的例子,说 明该方法的可行性和正确性.Abstract: The problem to design reduced-order controllers for a class of control problems is studied for linear time-invariable plants based on LMI (linear matrix inequalities). A new upper bound of the order for reduced-order controllers is proposed. The bound is applicable to both standard and singular control problems. Due to the constructive proof, an algorithm to construct the controller can be obtained. Finally, simple examples are given to show practicality and correctness of this approach.
